Application "filed April 24, 1925. Serial No. 25,565. a

This invention relates to tubular cores for the purpose of inserting cotton batts or other filling material into tubular envelopes,

such as the pleats of upholstery, its object being to provide for the operation of the core in a special manner-intended to facilitate the handling of'the filling material inserted bythe core into a tubular envelope and the removal of the core from the en:-

velope after the insertion of suchfilling, the

said invention being a modification 01' improvement of the device disclosed and illustrated in my co-pendin-g application, Serial No. 25,566 filed April 24:, 1925; v

The said invention resembles thatdisclosed in the said co-pending application referred to in that it comprises a 'longitudinallydivided tube,.one part of which is capable of contraction or expansion relative to the other part thereof so that the cross sectional'area may be varied to all intents and purposes throughout the length of the tube and a tubular flared receiver is provided through which filling'material may be entered into the tube, but in the present device the upper member of the tube is not recessed or cut away at the forward end thereof to give access to thefilling material so that it may be held while the said core is withdrawn from a pleat; the present invention having as one of its objects to dispense with such lopenings or recesses at the forward end of the core so 'thatthe filling material will be effectively enclosed at thispoint when being introduced into a tubular envelope and such introduction rendered easier .of accomplishment. The said invention further aims to provide for the movement of one of the members longitudinally with respect to the other of the members 'prior'to the withd'rawal ofthe core from the tubular envelope so that manual pressure maybe applied to the end of the filling material'in the desired Y manner. I e 7 I It is also an objecto'f the said invention to provide means whereby thisslidingof one of'the core members with respect to the other may beeifectedfin"anflunobtrusive or practically automatic. manner by an operator as aresult ofthe aaction jof-pulling on the de-. vice to efiectiitsjremoval from" a tubular H envelope;' the' invention,"to that end',-contion; a.

templating the use of a slide mounted upon Still further'objects subsidiary to "or re-- sulting from the aforesaid objects, or from the construction or operation of the said invention as it may be carried into eifect, will become apparent as the said invention is hereinafter further disclosed.

In carrying the said invention into efi'ect I'may provideatubular core longitudinally divided into upper and lower opposed trough-shaped members having their outer ends normally flush with one another, a flared tubular handle portion or receiver being adaptedto the rearward end of the lower trough-shaped portion and acting as the guide through which filling material is fed to the said divided tubular core, and a slide longitudinally movable on said receiver and adapted to be grasped with "thereceiver by an operator, said slidebeing connected, as by a compound hinge, to; the upper troughshaped member of the divided tubular core whereby the said upper member may be moved rearwardly of said lower member by an operator in], the act of efiecting withdrawal 'of the core from a tubular envelope. I All of .which is more particularly described and ascertained hereinafter, byway panying drawing, wherein Figure 1 is a plan of a'tubularenvelopefilling core embodying the said invention; ,Figure 2 is aside elevation of the same; Figure 3 is a' similar viewto Figure 2, with-the parts in 'a relatively varied 'posi Figure 4 is a fragmentary vertical section of the device,'with the parts in the positions indicated .in FigureB; and y i "Figure 5 isfafragmentary plan View of the fo-rward'end of the core with the parts inthe positions indicated in Figure 3.'

"Similar characters of reference indicate of example, having reference tothe acco1'n-- similar parts in the several figures 0f the drawing.

The core proper is indicated as being in the form of a longitudinally divided tube having upper and lower trough-shaped members 1 and 2, the lower member being provided with a rearwardly extending flared tubular portion 3 through which filling 4 may be fed to the tube, and which portion may be utilized as a hand grip by an operator in filling tubular envelopes.

Normally, as will be apparent from Figures 1 and 2, the forward end of the upper member is flush or approximately flush with the forward end of the lower member so that thesaid forward ends of the tube members substantially embrace the filling material at this point, and in the operation of filling tubular envelopes the parts are maintained in these relative positions while the core is inserted into the envelope and therefore little contact is established between the filling and the envelope during such operation.

It is, however, desirable that provision be made for permitting pressure to be applied through the envelope to the end of the filling during the extraction of the core from the envelope .to preventthe filling being also extracted, and for such purpose I have provided for the rearward movement of the member so that the forward end of the filling will. be uncovered by the said upper member. 7

To facilitate such movement of the said upper member I indicate it as being attached, preferably by a compound hinge member 5, to a slide 6 having tongues 7 entering elongated slots 8 in the member 3. This slide is also provided with an upwardly projecting tongue or abutment 9 at its rear end so that, in the gripping of the member 3 by the operator in utilizing the said core, the hand extends over the said slide 6 and engages the abutment 9. It will be obvious that this arrangement permits of the upper member 1 of the core being drawn rearwardly in the suggested manner by the action of the hand in commencing to move the core rearwardly to withdraw it from a tubular envelope, thus effecting a preliminary retracting of the said upper member 1, upon the completion of which retraction the further movement of the hand in the same direction results in the rearward movement of the core as a whole.

The retracted position of the upper memher is well illustrated in Figure 3, which shows the disclosure of the forward end 9 of the filling. A tubular envelope 10 is indicated in dotted lines in F i ures 2 and 3.

The disclosed arrangement facilitates the insertion of filling into a tubular envelope by enclosing it substantially at the forward end, although providing, at the time required, facility for engaging the end of the filling during the retraction of the core from said envelope and is of a simple and positive operable nature very unlikely to get out of order and admitting of cheap construction.

This invention may be developed within the scope of the following claims without departing from the essential features of the said invention, and it is desired that the specification and drawing be read as merely illustrative and not in a limiting sense, except as necessitated by the prior art.

What I claim is 1. A device for the insertion of filling into tubular envelopes, comprising a tubular receiver, a lower elongated trough-shaped member extending forwardly of said re ceiver, and an upper member extendin thereover from said receiver to the forward end of said lower member and slidable rearwardly relative thereto.

2. A device for the insertion of filling into tubular envelopes, comprising a tubular receiver, a lower elongated trough-shaped member extending forwardly of said receiver, and an upper inverted trough-shaped member extending thereover from said receiver to the forward end of said lower member and slidable rearwardly relative thereto.

3. A device for the insertion of filling into tubular envelopes, comprising a tubular receiver, a longitudinally divided tubular core comprising upper and lower members, the lower member rigidly extending from the forward end of said receiver, and the upper member being slidably connected to said receiver whereby it is rearwardly movable over said lower member.

4. A device for the insertion of filling into tubular envelopes, comprising a tubular receiver, a lower elongated trough-shaped member extending forwardly of said receiver, and an upper member extending thereover from said receiver to the forward end of said lower member, a rearwardly slidable member on said receiver, and a hinge connecting said upper member to said slidable member.

5. A device for the insertion of filling into tubular envelopes, comprising a tubular receiver, a lower elongated trough-shaped member extending forwardly of said receiver, an upper member extending thereover from said receiver to the forward end of said lower member, a rearwardly slidable member on said receiver adapted to be grasped by the hand of an operator, an abutment on said slidable member whereby rearward movement of the hand relative to said receiver may be imparted to said member, and means connecting the upper member of said core to said slidable member.

6. A device for the insertion of filling into tubular envelopes, comprising a tubular receiver, a lower elongated trough-shaped member extending forwardly of said receiver, an upper member extending thereover from said receiver to the forward end of said lower member, a rearwardly slidable' member on said receiver adapted to be grasped by the hand of an operator, an abutw 'ment on said slidable member'whereby rearward movement of the hand relative to said receiver may be'jimparted to said member, 10 and means hingedly connecting the upper member of saidcore to said slidable member. In testimonyiwhereof I affix my signature. f "GILBERT C. MCCULLOUGH.
